Compromising of resolution and contrast in obstructed Cauchy aperture and its application in confocal microscopy
Hamed, Abdallah;
Abstract
We designed an obstructed Cauchy filter to improve the microscope resolution, and we
calculated the point spread function (PSF) considering the Fourier transform operation
deduced from the known Fraunhofer diffraction. Then, we computed the coherent transfer
function (CTF) from the autocorrelation of the modulated Cauchy aperture. We applied the
modulated Cauchy pupils to a confocal scanning laser microscope (CSLM) and examined
the obtained images. We compared the images with the case of uniform circular apertures.
We used the MATLAB code to make all the images and plots
